It’s time to review the SSIDs you have in use!!

How many SSID/WLANs (Wireless LAN) do you have running on your wireless network? If you are like most, you have more then you should. Cisco wireless networks can support up to 16 SSIDs on a single access point (AP). With 16 SSIDs running on a single AP, the channel is about 60% utilized without any clients. This only leaves 40% of the channel to service clients.

Even with N data rates, I feel like my wireless network should be faster. I have coworkers that demand wired connections for meetings and temporary staff due to the slow wireless performance. Depending on the location I may have 8-10 active SSIDs. I did not setup the wireless network, so I don’t know why we have all of the SSIDs that we have. I do know that we have some for the older equipment and others for specific purposes like restricting user access.

After looking into the number of clients on each SSID, I found multiple SSIDs that were not being used. A couple SSIDs only had a couple clients. In one location I found two Cisco 7921 IP Phones on a test SSID instead of the SSID they should be on. They were the only devices using that SSID, what a waste of bandwidth.

After doing my research at each site, I discovered that I could delete about 3 SSIDs at each location.

I’m looking forward to the performance increase by deleting these SSIDs.

Maybe it’s time for you to audit your wireless network. Do you still need all of those SSIDs? You never know, you may be the Wireless Hero by improving the performance without spending any money!!

If you reduce the number of SSIDs please post the results that you find! I’m interested in reading about your results!!
